What Plumbing Services Does Larry's Plumbing Offer in Rockwall, TX?
We handle the full range of residential and commercial plumbing in Rockwall, TX — from a dripping faucet to a full sewer line replacement. Here's a complete breakdown.
1. Drain Cleaning in Rockwall, TX
Clogged and slow drains are the most common plumbing service call we receive in Rockwall, TX. Kitchen drains clog with grease and food debris. Bathroom drains collect hair, soap scum, and mineral buildup. Main sewer lines back up from root intrusion, grease accumulation, and structural pipe problems.
We don't just snake drains and call it done. Every drain cleaning call in Rockwall starts with a diagnosis:
- Camera inspection — for recurring or severe clogs, we run a camera down the line to see exactly what's causing the blockage (roots, grease, collapsed pipe, bellied section)
- Hydro-jetting — high-pressure water scour that strips grease, scale, and soft blockages from pipe walls; the most thorough cleaning method available
- Flex-shaft drain machine — mechanical cable cutting that physically removes hardened blockage material, including tree roots
- Standard auger/snake — for simple single-fixture clogs
Rockwall, TX homes built before 1990 often have clay sewer laterals that are especially vulnerable to root intrusion. If your drains keep clogging every few months, the issue is structural — camera inspection will show why.

2. Water Heater Repair and Replacement in Rockwall, TX
Water heaters in Rockwall, TX deal with moderately hard water — the mineral content here is enough to cause significant sediment buildup inside tank-style heaters over time. That sediment causes the characteristic rumbling and popping sounds, reduces heating efficiency, and shortens tank life.
Common water heater problems we repair in Rockwall, TX:
- No hot water — typically a failed heating element (electric) or thermocouple/gas valve (gas)
- Lukewarm water or fast hot water runout — sediment buildup, undersized tank, or a failed lower element
- Rust-colored water — anode rod depletion, tank interior corrosion; often means the tank is near end of life
- Popping or rumbling sounds — sediment firing on heating elements; tank flush may extend life
- Water pooling at the base — pressure relief valve discharge, failed drain valve, or tank body corrosion (replace)
- High utility bills — failing insulation, faulty thermostat, standby heat loss
Tank water heater replacement in Rockwall, TX: We stock 40, 50, and 75-gallon residential units. Most replacements are completed in 2–3 hours including haul-away of the old unit.
Tankless water heater installation in Rockwall, TX: Tankless units (Navien, Rinnai, Bradford White) eliminate standby heat loss and provide unlimited hot water. Rockwall homes with high hot water demand — large families, soaking tubs, multiple simultaneous showers — typically see the fastest payback on tankless.

3. Leak Detection in Rockwall, TX
Rockwall, TX sits on expansive clay soil — the same soil that makes North Texas foundation work so common. That clay moves with every wet season and every drought, and those movements stress the buried pipes beneath your slab.
Slab leaks — breaks in supply or drain lines running under your concrete foundation — are unusually common in Rockwall-area homes. They're also unusually easy to miss until serious damage has occurred.
Warning signs of a leak in your Rockwall home:
- Water bill up 20% or more with no change in usage
- Water meter moves when every fixture in the house is shut off
- Warm or hot spots on tile or concrete floors
- Sound of water running inside walls or under floors when nothing is on
- Unexplained mold or mildew smell at the base of walls
- Low water pressure that developed gradually
We use non-destructive leak detection: pressure testing to confirm a loss and acoustic listening equipment to locate the leak precisely — so we're cutting concrete exactly where we need to, not going on a fishing expedition.
Leak detection methods we use in Rockwall, TX:
- Pressure testing (supply and drain)
- Acoustic leak detection
- Sewer camera inspection
- Hydrostatic drain testing
